Introduction to Yogacara Buddhism by Thomas Tam from the Asian American / Asian Research Institute (The City University of New York). "Hsuan Tsang, the famous Chinese monk from the Tang dynasty, traveled from China to India to learn Yogacara Buddhism. He crossed deserts, mountains, rivers and spent eighteen years before his triumphant return to his country and began the daunting task of translating the sutras and commentaries that he brought back. One of the most important exposition, “Vijnaptimatratasiddhi-Trimsika”, was written by Vasubandhu who, together with his brother, Asanga, established and developed the teachings of Yogacara."
